ISO/NP 25329 Thermal insulation products — Polyester fibre mat and board — Specification

Scope

This document provides the requirements for factory-made products of polyester fibre thermal
insulation mat or board products for buildings. It includes determination of product characteristics
covering procedures for evaluation of performance, conformity, marking, labelling and packaging.
This document is limited to man-made polyester fibre thermal insulation products containing more than
65% (by mass) of man-made polyester fibre, with or without facings. The product is used where the
continuous service temperature of the insulation substrate is bounded by the temperature range 40 °C
to + 110 °C.
Products covered in this document may also be used in prefabricated thermal insulation systems and
composite panels; the performance of systems incorporating these products is not covered.
This document does not purport to address all the health and safety aspects associated with its use.
Anyone using this Standard has the responsibility to consult the appropriate authorities and to establish health and safety practices, in conjunction with any existing applicable regulatory requirements, prior to its use.

Purpose

Polyester mats are mainly manufactured from polyester fibre, a safe, non-toxic, allergy friendly,
lightweight material having high tensile strength, robustness and is unaffected by moisture. Polyester
mats are itch free, contain no formaldehyde binders, and require no protective clothing to install. All of
this makes them a safe insulation option for all to use.
Polyester mat also have a Zero Ozone Depleting (ODP) rating, contain negligible Volatile Organic
Compounds (VOC’s), further 80% of the fibres that go into Polyester mat are recycled from plastic bags ,bottles and other packaging materials, so globally they are environmentally safe and beneficial.
Polyester insulation products have been using widely in Australia, Japan, UK ,China, New Zealand ,
USA and other many countries . There are currently no national standards or ISO standards focused
on Polyester fibre thermal insulation products. Accordingly, a Polyester fibre thermal insulation
products ISO standard is needed
